The comet formed in a cold and distant part of the early Milky Way up to 12 billion years ago, putting it just under 2 ...

The interstellar comet 3I/ATLAS is leaving our solar system for good. Here's what to know about its journey and NASA's ...

Interstellar Comet 3I/ATLAS, the third known object to visit our solar system from another star, carries a chemical signature ...

Learn how ALMA observations revealed unusually high levels of methanol in interstellar comet 3I/ATLAS and what the molecule’s chemistry may reveal about how icy bodies form around other stars.

One rare comet has done two jobs at once: it has widened the scientific map of how other planetary systems form, and it has exposed how dependent that science remains on a clear, trackable sky. Comet ...

It ain't from around these parts of space.

Comet 3I/ATLAS continues to make astonishing headlines, thanks to new findings from astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA). This new research reveals that 3I/ATLAS ...

Interstellar Comet 3I/ATLAS is the gift that keeps on giving. A snapshot of the space that lies beyond the solar system, it brings clues to other stars, other worlds and the galaxy we call home. Just ...

Analysis of the tail of 3I/Atlas reveals that it contains an anomalous proportion of methanol, a class of alcohol used in fuels.

Lead researcher Nathan Roth said the image shows the comet is “bursting with methanol in a way we just don’t usually see.” ...

Astronomers using ALMA have found large quantities of methanol in comet 3I/ATLAS, making it one of the most alcohol-rich ...

Comets are pristine remnants left over from the solar system's formation 4.6 billion years ago, rather than younger fragments created by collisions between larger bodies, a new study suggests. The ...
